SN 1988A is (with exception of the well-observed SN 1987A) the only type II SN for which observations of the late tail of the light curve are presently available. This SN showed a brief spike in the early visual light curve followed by a long plateau lasting for about 3 months. Spectra taken during both the plateau and the postplateau phases

SN 1988A in M58 - Departure from Co-56 decay 700 days after explosion
Observations of SN 1988A in M58 are presented which show a remarkable departure from Co-56 decay in the optical light curve starting about 700 days since explosion. It is shown that the departure cannot be explained by the contribution from other radioactive isotopes to the late luminosity, and fluorescence in nearby clouds can be excluded as the

Solar coronal loop oscillations: theory of resonantly damped oscillations and comparison with observations
One of the proposed damping mechanisms of coronal transverse loop oscillations in the kink mode is resonant absorption as a result of the spatial variation of the Alfvén velocity in the equilibrium configuration. Analytical expressions for the period and the damping time exist for 1-D cylindrical equilibrium models with thin non-uniform

Solar encounter
The prime objectives of the workshop were to: inform the community about the science opportunities of the Solar Orbiter mission; to provide a forum for sharpening and focussing the science goals; allow the hardware groups and instrument proposers to critically review the payload; establish international contacts and collaborations.

Solar polarimetry through the K I lines at 770 nm
We characterize the K I D1 & D2 lines in order to determine whether they could complement the 850 nm window, containing the Ca II infrared triplet lines and several Zeeman sensitive photospheric lines, that was studied previously. We investigate the effect of partial redistribution on the intensity profiles, their sensitivity to changes in
